Hey folks,
I'm using CGI mapserv and I'm trying to find a way to do variable
substitution in the GDAL PROCESSING line to allow dynamic scaling of a
raster image:
PROCESSING "SCALE=%mintemp%,%maxtemp%"
and specify this with my &mode=map request:
&mintemp=31000&maxtemp=33000
However it doesn't seem to pick up on the CGI variables. I've noticed
Charlton's recent messages about other mapfile objects not taking cgi
substitution variables, could PROCESSING be one of them?
So taking another route, I tried to use the mapfile runtime configuration like:
&map_sst_processing=SCALE=31000,33000
and again with the "=" url-encoded
&map_sst_processing=SCALE%3D31000,33000
Neither of which worked.
Is there any way to dynamically configure the PROCESSING object with
mapserv CGI or are we limited to hardcoding it at the moment?
